I posted what seemed a trivial request to info-telecom a while back, re
a possible schematic for a simple "off-hook" indicator so that other residents
of my house wouldn't use the phone when my modem was in use. The preferred
method was to have an LED showing a off-hook and/or an on-hook status, and
either built into the phone or being able to tap into the line at any point in
the circuit. Please mail any answers to me, and I'll post appropriately to
info-telecom.
